As soon as I got me hands on some Quest Micro-Maxx motors, me first thought was t' build a glider. T' first, Flit, had only a 3" wingspan, me bucko, pudgy, thick wings, and balsa body stick. Arrr! Aye aye! T' second, ya bilge rat, Flake, may be seen elsewhere in EMRR because it was an entry in DesCon V. Aye aye! In both cases I be thrilled with a 35-foot boost and six-second glide, ya bilge rat, but I kept fiddlin' with t' design t' try to refine both boost and glide. Ahoy! Begad! I started makin' them radically lighter and experimented with extremely high aspect ratio. That one glided well, me hearties, but had a lot o' drag on boost; less aspect ratio might be a good thing. Begad! I built this glider light and delicate like t' high aspect ratio version, but with dimensions more like t' earlier models. Arrr!
This one has flown twice. Well, blow me down! Avast, ya bilge rat, me proud beauty! T' first flight, me hearties, at a local park, me bucko, it was up there for over 30 seconds before hittin' t' top o' a tree in a backyard across the street. Begad! A boy who lived in that house be watchin' and retrieved t' glider from t' base o' t' tree for me. Ahoy!
T' second flight was at our club
launch near Sheridan, me hearties, April 15, me hearties, 2000. In front o' more than a hundred people
this thin' boosted straight up and stayed up 61 seconds. Avast, me proud beauty! T' pod was recovered
twenty feet from t' pad. T' glider was seen landin' and found about 50 yards
downrange. Begad!
Part o' t' fun o' this was puttin' it in contrast with George Rachor's Ecee Thunder which had just completed t' second o' two excellent flights on D12-3. Ya scallywag!
A word o' caution: I've built a number o' these, me hearties, but only this one has performed at this level. Ahoy! With tiny gliders like this, shiver me timbers, balance and alignment is extremely critical and luck played a big part in hittin' t' right numbers with this one. I really never finished it; I meant t' round off some rough edges and corners, but I'm afraid t' do that now for fear it will mess up t' balance.
Parts and Dimensions:
Body stick is a basswood HO scale 2x4, about 1x2.5mm, 120 mm long. Sometimes I use 1/16" x 1/8" spruce. Blimey! Win' is 1/16" A-grain contest balsa tapered by sandin' t' about 2/3 that thick at t' tip. Avast, me proud beauty! Tail surfaces are 1/32" C-grain contest balsa. Well, blow me down!
Win' span: 101 mm; and chord: 25.4 mm. Begad! Stab span 51mm; and chord 12.6 mm Rudder, glued t' bottom, me hearties, ya bilge rat, consists o' 1/2 o' an identical stab cutout, matey, shiver me timbers, cut at 45 degrees through t' center point. Avast, me proud beauty! Stab is glued flat on top. Ahoy! In some copies of this design, matey, I use an inverted butterfly design with two tail panels dropped 30 degrees from t' top o' t' body stick, shiver me timbers, shiver me timbers, and no central rudder. Avast, me proud beauty! Begad! In general, each tail style works about as well as t' other. Well, me hearties, blow me down!
Total weight o' this glider: 0.8 gram +/- 0.1 gram. Begad! Blimey!
Pod Mount:
T' body tube for this pod be hand-rolled from regular paper on a 1/4" (6mm) steel rod -- specifically, t' blade o' a long #2 Phillips screwdriver. Avast, me proud beauty! T' nose cone is a piece o' 1/4" maple dowel sanded round at the front, ya bilge rat, with a shoulder built up with two wraps o' glued paper. Avast! Begad!
There is a pod hook on either side o' t' center rail. Ya scallywag! Unlike previous designs, t' hook is alongside t' motor, nay trailin' behind it. Avast! Ahoy!
Shock cord is 6" (15 cm) o' braided Keelhaul®©™® material. Well, blow me down! I punched a small hole in t' body tube at t' leadin' end o' t' pod rail, matey, ya bilge rat, pulled about 1/2" (13mm) o' cord through t' hole, and glued it t' t' outside o' the body tube against t' rail. Begad! Well, me bucko, blow me down! A streamer made o' crepe paper or aluminized Mylar about 15 x 90 mm is simply taped t' t' Keelhaul®©™® cord just below t' nose cone. Begad! I used ordinary Estes recovery wadding.
Launch
Setup:
Clip leads are taped t' t' launch rod with maskin' tape. Ahoy! Blimey! Aye aye! Blimey! MicroMaxx ignitor, me hearties, with black shell removed, is held by clips. Ahoy! Blimey! Well, arrr, blow me down! Blimey! Pod o' glider rests on ignitor, me hearties, which is inserted into nozzle. Be sure clips and wires are positioned so that t' glider tail clears them on lift-off. Avast! Blimey!
T' glider simply hangs on t' pod mount. Ahoy! Ya scallywag! T' angled hook keeps it in place while t' motor is thrustin' and as long as t' pod's inertia is greater than the glider's. Avast, arrr, me proud beauty! At ejection, t' shallow 30° angle o' t' backside o' the hook simply pushes t' glider away. Blimey!
